I'm nearing the part where I can start forming brass and I wanted to ask if their are any tips on necking down brass properly. The rifle parts are all here and are going off to the gunsmith this morning. The plan is to take Lapua 8x57 virgin brass and neck it down to 6.5 then blow the shoulder out to 30 deg. Dave Kiff of PTG calls it 6.5x57BR; BR for 30 deg shoulder. Whidden made up a set of custom bushing dies of me and I've got about 4-5 bushings to size down the neck in steps; about .014" or .015" steps. I figure plenty of Imperial Sizing Wax to easy the work. I've then got the Whidden Hydraulic Form die to blow out the shoulder before 1st firing.
Any advice or tips would be great and thanks in advance.
Alan
